Abstract: A touch sensing device comprises a common electrode divided into a plurality of sensor electrodes, a plurality of sensor lines respectively connected to the plurality of sensor electrodes, a feedback voltage transmitter, and a common voltage compensator. The feedback voltage transmitter includes a feedback line, a plurality of switching elements configured to selectively connect the sensor lines to the feedback line, and a feedback control line configured to control selection of the switching elements. The common voltage compensator is configured to receive a feedback voltage supplied to the sensor lines through the feedback line while the sensor lines are connected to the feedback line through the plurality of switching elements, and compensate the feedback voltage to a reference voltage level.
